1884, an Englishman, Edward butler, added a power device to his bicycle and made a tricycle powered by kerosene. 1885, the German "father of automobiles" made a three-wheeled motorcycle driven by a single-cylinder air gasoline engine. On August 29th of the same year, he obtained a patent for this invention. Therefore, Daimler is recognized by the world as the inventor of motorcycles. Daimler's first motorcycle was driven by a four-stroke internal combustion engine. The working pit of the cylinder is 264 cubic centimeters. At 700 revolutions per minute, the power can reach 0.5 horsepower and the speed can reach 65,438+02 kilometers per hour. The car is made of wood, the rear wheel is driven by a belt, and there are auxiliary support wheels on both sides. In view of Daimler's irreplaceable historical position, after his death, the Wudenberg branch of the German Engineer Association erected his monument in Sheutat Square, where he drove his first motorcycle.
100 years ago, the gasoline engine at that time was still in a low-level and naive state, and the vehicle manufacturing at that time was still in the stage of carriage technology. Primitive motorcycles are quite different from modern motorcycles in appearance, structure and performance. The original motorcycle frame was made of wood. Judging from the wood grain, it is made by carpenters and the wheels are also made of wood. The outer layer of the wheel is covered with a layer of iron. There are several square wooden frames in the middle and lower part of the frame, on which the engine is placed. There are small support wheels on both sides of the wooden frame to prevent it from toppling when it is still. Therefore, the car actually landed on four wheels. The engine cooled by a single-cylinder fan drives the rear wheel forward through two-stage reduction transmission of belt and gear. The car seat is saddle-shaped and covered with leather. The working volume of engine cylinder is 264mL, and the maximum power is 0.37kW(700r/min), which is only 1/5 of that of modern simple motorcycle. Speed 12km, not much faster than walking. Because there were no buffers such as springs at that time, this kind of car was called "bone shaking car". As you can imagine, driving on the stone street in the19th century is worse than execution. Although the original motorcycle was so simple, since then, motorcycles have been constantly changed and improved. 100 years ago, hundreds of millions of descendants of modern motorcycles have emerged.
